Abstract

The present invention relates to a cracking method of hydrocarbon oil, including contact of hydrocarbon oil with catalyst under the cracking condition. Said catalyst is a cracking catalyst containing laminar clay or mixture of said cracking catalyst containing laminar clay and existent cracking catalyst. The described cracking catalyst containing laminar clay is prepared by adopting the following steps: mixing expandable clay, modifying component, pseudo-thin hydrargillite and water, pulping for 0.1-10 hr. to obtain a slurry liquor, ageing for 0.1-10 hr. at 50-85 deg.C, drying, forming, washing with water, ageing, drying and roasting so as to obtain the invented catalyst. The described modifying component can be selected from hydroxyl polymer of silicon, aluminium, zirconium and titanium or substance containing the described hydroxyl polymer.

Description

field of invention [0001] The invention relates to a method for cracking hydrocarbon oil. Background technique [0002] In recent years, the tendency of crude oil to become heavier has become more and more serious. Because in crude oil, fractions with a boiling point above 400°C are difficult to enter the pores of zeolite, in order to improve economic benefits, the cracking capacity of existing zeolite-containing cracking catalysts for heavy oil can no longer meet the requirements. Adding layered clay components into the cracking catalyst can improve the heavy oil cracking ability of the cracking catalyst. [0003] CN1031029A discloses a layered clay molecular sieve catalytic cracking catalyst, which is composed of an active component, a support component and a binder component. Wherein, the active component is accounted for catalyst weight 1-100%, preferably 40-60% layer column molecular sieve with regular interlayer mineral structure including r...
